Abstract: The present invention discloses a scheme of integrating Information Centric Networking Mechanisms into a Content Distribution Network. Methods are provided respectively for an internet service provider domain name server, ISP DNS, a publisher name server, an auxiliary network node, a client node, and an edge cache. According to the present invention, in a resolution procedure, a client node asks the ISP DNS to resolve a content name, then the ISP DNS queries the publisher name server to get a first resolution result which will be then transmitted by the ISP DNS to the auxiliary network node to obtain a second resolution result. At the end of the resolution procedure, the second resolution result is transmitted back to the client. During a delivery procedure, the client node may transmit a request comprising the content name and the second resolution result to an edge cache that is indicated in the second resolution result.

Abstract: A method of evaluating an additional service for a device (11) of a user of a telecommunication system is described. The device (11) supports one or more basic services. The kind of basic service/s being provided by the device (11) is examined. An additional service that could be combined with the basic service/s already supported by the device (11) is searched.

Abstract: The invention relates to a method for operating a symmetric network address translation NAT (100) setting up sessions between a user terminal (110-1, 110-2) and a server (120-1, 120-2). If a new session is initiated by said user terminal an external IP-address (C) and port (D) representing the desired destination server as well as a public NAT-IP address (X) are determined. Further, a public NAT-IP port is selected. Finally, the NAT sets up the new session based on an appropriate entry representing said new session in a NAT table. In order to save available public NAT-IP ports a new session according to the invention not necessarily represented by a new public NAT-IP port, but by a tuple comprising the public NAT-IP address, the selected public NAT-IP port (Y), the external IP address (C) and the port (D). A new session is set up only if there is an entry of the whole tuple identifying said new session in said NAT-table.

Abstract: The invention concerns a method for providing features to the user of a telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) that is connected to a central unit (CU) whereby, if said telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is currently not interconnected via the central unit (CU), said telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) notifies the central unit (CU) at least about certain kinds of user activities, in case of such notification the central unit (CU) checks whether it is currently interconnected to another telephone assigned to the same subscriber as said notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) and in case of the existence of such interconnection, the notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is interconnected in parallel to this interconnection, and if said notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is not a telephone for digital communication, the other telephone is a telephone for digital communication.

Abstract: A focusing device with a refractive index profile changing from the center of the focusing device towards its perimeter, is made of a material wherein the lateral refractive index distribution of the focusing device material is homogeneous and wherein the focusing device comprises holes for introducing a graded refractive index profile. This allows accurate control of the graded refractive index profile.

Abstract: The invention relates to a method for exchanging messages between an end subscriber and a text message server in a telecommunication network via even a conventional telephone device, which is connected to the text message server via a gateway with browser, which has means for voice recognition and for converting text into speech, and a service computer, wherein according to the end subscriber's instructions given by speech and/or via the keypad of the telephone device the gateway with browser contacts the service computer and from there downloads an electronic document, the gateway with browser converts indications, instructions and/or text messages from text into speech by means of the electronic document and outputs them on the telephone device and the gateway with browser receives instructions and/or messages which the end subscriber has input by speech and/or via the keypad of the telephone device, voice messages being converted into text messages in the gateway with browser, and also a telecommunication

Abstract: The present invention concerns a server and a method for transferring a message originating in a telecommunication network to an addressed subscriber. A telecommunication terminal sends a message to a server. The server inserts an address allocated to a TV set of the address subscriber to the message or encrypts the message by means of an encryption key allocated to a TV set of the address subscriber. In the following, a headend node of a TV broadcast network inserts the message into a TV signal and broadcasts the TV signal via a TV broadcast channel. A receiver unit assigned to the TV set of the addressed subscriber filters out the message and outputs the message on the TV set.

Abstract: The basic idea of the present invention consists of taking advantage in comparison with the waveguide itself of a different temperature dependency from a cladding layer made of e.g. polymer without being penalized by subsidiary effects. The insertion of an additional coating layer in between the cladding layer and the waveguide in accordance with the present invention limits among others an overlap of a mode field with said cladding layer when present in the waveguide.
